[0088] In some demonstrative embodiments, devices 102 and/or 140 may be configured according to one or more standards, for example, in accordance with an IEEE 802. Hay Standard, which may be, for example, configured to enhance the efficiency and/or performance of an IEEE 802.11-2016 and/or an IEEE 802.1 lad Specification, which may be configured to provide Wi-Fi connectivity in a 60 GHz band. [0089] Some demonstrative embodiments may enable, for example, to significantly increase the data transmission rates defined in the IEEE 802.11-2016 Specification and/or the IEEE 802.1 lad Specification, for example, from 7 Gigabit per second (Gbps), e.g., up to 30 Gbps, or to any other data rate, which may, for example, satisfy growing demand in network capacity for new coming applications.

[0090] Some demonstrative embodiments may be implemented, for example, to allow increasing a transmission data rate, for example, by applying MIMO and/or channel bonding techniques.

[0099] Some wireless communication Specifications, for example, the IEEE 802. Had Specification, may be configured to support a SU system, in which a STA may transmit frames to a single STA at a time. Such Specifications may not be able, for example, to support a STA transmitting to multiple STAs simultaneously, for example, using a MU-MIMO scheme, e.g., a DL MU-MIMO, or any other MU scheme.

[00100] In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more mechanisms, which may, for example, enable to extend a single-channel BW scheme, e.g., a scheme in accordance with the IEEE 802.1 lad Specification or any other scheme, for higher data rates and/or increased capabilities, e.g., as described below.

[00101] In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more channel bonding mechanisms, which may, for example, support communication over bonded channels.

[00102] In some demonstrative embodiments, the channel bonding mechanisms may include, for example, a mechanism and/or an operation whereby two or more channels can be combined, e.g., for a higher bandwidth of packet transmission, for example, to enable achieving higher data rates, e.g., when compared to transmissions over a single channel. Some demonstrative embodiments are described herein with respect to communication over a bonded channel, however other embodiments may be implemented with respect to communications over a channel bandwidth, e.g., a "wide" channel, including or formed by two or more channels, for example, an aggregated channel including an aggregation of two or more channels.

[00103] In some demonstrative embodiments, device 102 and/or device 140 may be configured to implement one or more channel bonding mechanisms, which may, for example, support an increased channel bandwidth, for example, a channel BW of 4.32 GHz, a channel BW of 6.48 GHz, a channel BW of 8.64GHz, and/or any other additional or alternative channel BW.

[00104] In some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, process, transmit and/or receive a Physical Layer (PHY) Protocol Data Unit (PPDU) having a PPDU format (also referred to as "EDMG PPDU format"), which may be configured, for example, for communication between EDMG stations, e.g., as described below.

[00105] In some demonstrative embodiments, a PPDU, e.g., an EDMG PPDU, may include at least one non-EDMG ("legacy") field, which may be identified, decodable, and/or processed by one or more non-EDMG devices ("legacy devices"), which may not support one or more features and/or mechanisms ("EDMG" mechanisms). For example, the legacy devices may include non-EDMG stations, which may be, for example, configured according to an IEEE 802. Had Standard, and the like.

[00106] In some demonstrative embodiments, the PPDU, e.g., the EDMG PPDU, may include a non-EDMG header (L-header) field, which may carry non-EDMG header information, for example, according to a legacy Specification, e.g., an IEEE 802.1 lad Specification, For example, according to a Clause 20 of an IEEE 802.11- 2016 Specification, and/or any other information.

[00107] In some demonstrative embodiments, the EDMG PPDU may include at least one EDMG header field, for example, at least a Header-A field, e.g., an EDMG- Header-A field, and optionally an EDMG Header-B field, which may be configured to carry EDMG information, for example, information required to interpret EDMG PPDUs, and/or any other information. [00108] Reference is made to Fig. 2, which schematically illustrates a structure of an EDMG PPDU 200, which may be implemented in accordance with some demonstrative embodiments. In one example, devices 102 and/or 140 (Fig. 1) may be configured to generate, transmit, receive and/or process one or more EDMG PPDUs having the structure of EDMG PPDU 200.

[00109] In some demonstrative embodiments, as shown in Fig. 2, EDMG PPDU 200 may include a non-EDMG portion 210 ("legacy portion"), e.g., as described below.

[00110] In some demonstrative embodiments, as shown in Fig. 2, non-EDMG portion 210 may include a non-EDMG (legacy) Short Training Field (STF) (L-STF) 202, a non-EDMG (Legacy) Channel Estimation Field (CEF) (L-CEF) 204, and/or a non- EDMG header 206, e.g., a Legacy header (L-Header).

[00111] In some demonstrative embodiments, as shown in Fig. 2, EDMG PPDU 200, may include an EDMG portion 220, e.g., as described below.

[00112] In some demonstrative embodiments, as shown in Fig. 2, EDMG portion 220 may include an EDMG header, e.g., an EDMG-Header-A 212, an EDMG-STF 214, an EDMG-CEF 216, an EDMG-Header-B 218, a data field 219, and/or one or more beamforming training fields, e.g., one or more AGC fields 222 and/or one or more TRN fields 224.

[00113] In other embodiments, EDMG portion 220 may include some or all of the fields shown in Fig. 2, and/or one or more other additional or alternative fields.

[00114] In other embodiments, the EDMG PPDU 200 may include some or all of the fields shown in Fig. 2, and/or one or more additional or alternative fields.

[00115] In one example, TRN fields 224 may immediately follow data field 219, e.g., if EDMG PPDU 200 does not include AGC fields 222.

[00116] Referring back to Fig. 1, in some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, process, transmit, and/or receive one or more PPDUs, e.g., according to EDMG PPDU structure 200 (Fig. 2), including an EDMG header, for example, an EDMG-Header-A, e.g., as described below.

[00117] In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more operations, e.g., of a process, to generate, process, transmit, and/or receive an EDMG-Header-A for Control Mode PPDUs, for example, PPDUs with a Modulation and Coding Scheme 0 (MCSO), e.g., as described below.

[00118] In other embodiments, devices 102 and/or 140 may be configured to implement one or more operations, e.g., of a process, to generate, process, transmit one or more additional or alternative header fields of one or more additional or alternative types of PPDUs.

[00119] In some demonstrative embodiments, the EDMG-Header-A of a Control Mode PPDU may be defined, for example, such that the EDMG-Header-A may occupy part of a first transmitted codeword, e.g., a first low-density parity-check codeword (LDPC) codeword, and at least part of a second transmitted LDPC codeword, e.g., a second LDPC codeword, for example, as described below.

[00120] In other embodiments, the EDMG-Header-A may be allocated to any other additional or alternative codewords, and/or to any other number of codewords.

[00121] In some demonstrative embodiments, one or more fields of the EDMG- Header- A may occupy one or more last octets of the first codeword, for example, the last 6 octets of the first codeword, or any other number of octets, e.g., as described below.

[00122] For example, the last 6 octets of the first codeword may include octets, which may be alternatively used for data transmission of a DMG PPDU.

[00123] In some demonstrative embodiments, in a second codeword, e.g., subsequent to the first code word, one or more other fields of the EDMG-Header-A may occupy one or more octets, for example, a certain number of octets, e.g., two or three octets, or any other number of octets.

[00124] In some demonstrative embodiments, different subfields of the EDMG- Header-A may be allocated to at least the two codewords, for example, in a way that some or all of the subfields that carry information are transmitted in the first codeword, and at least a Header Check Sequence (HCS) is transmitted in the second codeword, e.g., as described below.

[00125] For example, according to this configuration, a device receiving the PPDU ("an EDMG receiver") may have access to the information carried in the EDMG- Header-A in the first codeword, e.g., which may also carry the L-Header. The EDMG receiver may know if the EDMG-Header-A in the first codeword is correct, for example, only after checking the HCS in the second codeword. One advantage of this procedure is that the EDMG receiver may have access to the information carried by the EDMG-Header-A, for example, as soon as the first transmitted LDPC codeword is decoded.

[00126] In other embodiments, some or all subfields of the EDMG-Header-A may be allocated to a plurality of codewords according to any other allocation and/or scheme. In one example, one or more subfields of the EDMG-Header-A that carry information may be allocated to the second codeword.

[00172] In some demonstrative embodiments, the structure of EDMG PPDU header 300 including first codeword 301 and second codeword 320 may be configured, for example, to allocate different subfields of an EDMG header, e.g., the "EDMG- Header-A", to at least two codewords to be used for transmission of the EDMG PPDU, e.g., as described below.

[00173] In some demonstrative embodiments, as shown in Fig. 3, a non-EDMG header, e.g., L-header 302, may be assigned to first codeword 301. [00174] In some demonstrative embodiments, as shown in Fig. 3, one or more subfields 304 of an the EDMG-Header-A, for example, all subfields of the EDMG- Header-A that carry information, may be allocated to the first codeword 301.

[00175] In one example, the EDMG-Header-A may be allocated to codewords, for example, according to a codeword allocation scheme, which may be configured, for example, such that most or all the EDMG-Header-A bits that carry information, e.g., all bits but reserved and HCS bits, may be transmitted in the first codeword 301. In other embodiments, any other additional or alternative bits and/or fields of the EDMG Header A may be allocated to the first codeword.

[00176] In some demonstrative embodiments, as shown in Fig. 3, the one or more subfields 304 may be assigned to the last 6 octets of first codeword 301.

[00177] In some demonstrative embodiments, as shown in Fig. 3, the one or more subfields 304 may include a BW field 311, a primary channel field 312, a length field 313, an EDMG TRN length field 314, an Rx TRN-units per each Tx TRN unit field 315, a field 316 to indicate a number of TRN subfields per TRN unit, and a field 317 including one or more reserved bits.

[00178] In some demonstrative embodiments, as shown in Fig. 3, the one or more reserved bits, e.g., 3 reserved bits, or any other number of reserved bits, may be allocated to the first codeword 301, for example, such that a total number of EDMG- Header-A bits allocated to the first codeword 301 may be 48, or any other number.

[00179] In other embodiments, one or more of the subfields 304 may have any other bit length, and/or subfields 304 may include only some of the subfields shown in Fig. 3 and/or one or more additional subfields.

[00180] In other embodiments, some of the subfields 304 may be allocated to the second codeword 320, and/or one or more other subfields of the EDMG Header A may be allocated to the first codeword 301.

[00181] In some demonstrative embodiments, as shown in Fig. 3, one or more other subfields of the EDMG-Header-A, for example, at least an HCS subfield 318, may be allocated to second codeword 320.

[00182] In some demonstrative embodiments, as shown in Fig. 3, HCS subfield 318 may be assigned to at least two octets of second codeword 320. [00183] In some demonstrative embodiments, HCS subfield 318 may be transmitted, for example, at least to allow a receiver station to detect decoding errors, e.g., in one or more subfields of the EDMG-Header-A, e.g., in the one or more of subfields 304.

[00184] In one example, the HCS 318 of the EDMG-Header A may be configured, for example, to allow a receiver of the EDMG PPDU to determine a correctness of a received EDMG-Header A, e.g., by applying a procedure similar to a procedure to detect the correctness of the L-Header 302.

[00185] In one example, the HCS subfield 318 may include, for example, a 16-bit HCS, for example, generated by a same HCS generator, which may be used for the L- Header 302, e.g., to allow ease of implementation. In other embodiments, the HCS subfield 318 may include any other suitable HCS of any other length and/or any other HCS generator may be used.

[00186] In other embodiments, one or more other additional or alternative subfields of a non-legacy header of a PPDU, e.g., the EDMG-Header-A of the EDMG PPDU, may be allocated to the second codeword and/or to another codeword, e.g., based on the length of the codewords, the length of the subfields, the length of the EDMG- Header-A and/or any other parameter and/or criterion.

[00187] In some demonstrative embodiments, as shown in Fig. 3, a total number of 43 bits, may be required to transmit the EDMG-Header-A information, for example, if all subfields except for the field 317, e.g., including the one or more reserved bits, and the HCS subfield 318, are to be transmitted. This number of bits is less than the number of EDMG-Header-A bits that can be transmitted in the 6 last octets of the first codeword 301, which includes 48 bits .

[00188] In some demonstrative embodiments, transmitting subfields 304 in the first codeword 301, and transmitting the HCS 318 in the second codeword 320, may allow a receiver station, e.g., device 140 (Fig. 1), to obtain the EDMG-Header-A information in the first codeword 301, for example, while the receiver station may be able to "validate" the EDMG-Header-A information, for example based on HCS 318, e.g., after decoding the second codeword 320 including HCS subfield 318.

[00189] In some demonstrative embodiments, it may be assumed in some use cases and/or scenarios that there may be a low likelihood of errors in the detection and decoding of the EDMG-Header-A, e.g., if an HCS of the L-Header 302, which is included in the first codeword 301 is being checked, for example, given the low code rate and/or large spreading factor used in the transmission of control mode PPDUs.

[00190] In some demonstrative embodiments, a receiver implementation, e.g., by device 140 (Fig. 1), may be able to use the EDMG-Header-A information in the first codeword 301, for example, even before "validating" the EDMG-Header-A information, which may be performed after processing the second codeword 320. In one example, if errors are detected once the HCS 318 is decoded, the receiver station could, for example, drop the packet.

[00191] In one example, a technical advantage of this configuration may be, for example, that an EDMG receiver may be allowed to have an access to the information carried by the EDMG-Header-A, for example, even once the first codeword is decoded. This may be advantageous, for example, compared to having information of the EDMG-Header-A transmitted in the second codeword 320, for example, which may require the receiver to wait until the decoding of the second codeword 320 to be able to correctly interpret the EDMG PPDU, which may cause significant delay/latency to a processing of an EDMG processor.

[00192] In one example, the EDMG-Header-A may include one or more subfields, e.g., some or all of the following subfields:

EDMG 8 Indicates the number of TRN-Units present in the TRN

TRN field of the PPDU

Length

RX TRN- 8 This field is reserved if the value of the EDMG TRN units per Length field is 0. Otherwise, this field indicates the each TX number of consecutive TRN-Units in the TRN field for TRN-unit which the transmitter remains with the same transmit

AWV.

P 2 Indicates the number of TRN sequences/subfields in a

TRN-Unit used for channel estimation.

M 4 Indicates the number of TRN sequences/subfields in a

TRN-Unit used for beamforming training

Reserved 5

HCS 16 Header Check sequence. Calculation of the header check sequence is defined in 20.3.7

Table 1

[00193] In other embodiments, the EDMG-Header-A may include some or all of the fields of Table 1, and/or may include one or more additional or alternative fields and/or elements, e.g., in addition to, or instead of, one or more of the fields or elements of Table 1.

[00194] In some demonstrative embodiments, assigning the different subfields of the EDMG-Header-A to codewords, e.g., to two codewords, may include, for example, one or more of the following criteria and/or rules:

• Assign all subfields of the EDMG-Header-A that carry information to a first codeword, e.g., codeword 301;

• Assign the HCS subfield, e.g., HCS subfield 318, to a second codeword, e.g., codeword 320;

• Alternatively, some bits of the HCS subfield could be assigned to the first codeword, for example, as long as the total number of EDMG-Header-A bits in the first codeword is no more than 48;

• One or more reserved bits could be assigned to the second codeword; • Assign one or more reserved bits to the first codeword, for example, in such a way that the total number of EDMG-Header-A bits in the first codeword is 48;

• Alternatively, no reserved bits might be allocated to the first codeword. In this case, the first codeword may contain the subfields of the EDMG-Header-A that carry information and possibly some bits of the HCS if necessary; and/or

• If the number of bits of the subfields of the EDMG-Header-A that carry information is greater than 48, some of the bits of the subfields, e.g., one or more subfields or part of a subfield, may be allocated to the second codeword.

[00195] Referring back to Fig. 1, in some demonstrative embodiments, device 102 may be configured to encode and modulate an EDMG PPDU header of an EDMG PPDU. For example, device 102 may be configured to encode and modulate EDMG PPDU header 300 (Fig. 3).

[00196] In some demonstrative embodiments, one or more portions of the EDMG PPDU, for example, one or more subfields of the EDMG-A-Header, may be encoded and/or modulated, for example, according to an encoding and modulation scheme of a Control Mode, e.g., in compliance with an IEEE 802. Had Specification. For example, the encoding and modulation scheme may include LDPC encoding, differential encoding, spreading by a factor of 32, and/or π/2-DBPSK modulation, e.g., for ease of implementation. However, in other embodiments, any other encoding and/or modulation schemes may be used.

[00197] Reference is made to Fig. 4, which schematically illustrates a coding and modulation scheme 400 of a header of an EDMG PPDU, which may be implemented in accordance with some demonstrative embodiments.

[00198] In some demonstrative embodiments, one or more of the operations of Fig. 4 may be implemented, for example, as part of a process of generating and/or transmitting a header field, e.g., a control mode header field, of an EDMG PPDU.

[00199] In some demonstrative embodiments, as shown in Fig. 4, a first codeword 402 may include a non-EDMG header (L-Header) 404 and a first portion of an EDMG header 406, e.g., the subfields 304 (Fig. 3) of the EDMG-Header-A 212 (Fig. 2).

[00200] In some demonstrative embodiments, as shown in Fig. 4, the first codeword 402 may include a total of 11 octets or 88 bits. [00201] In some demonstrative embodiments, as shown in Fig. 4, non-EDMG header (L-Header) 404 may include a total of 5 octets or 40 bits, e.g., including 24 information bits and 16 bits of an HCS 403 of the L-header 404.

[00202] In some demonstrative embodiments, the L-Header of EDMG PPDUs may be generated and transmitted using operations of the procedure of Fig. 4, for example, at least to ensure backward compatibility with a non-EDMG station.

[00203] In some demonstrative embodiments, as shown in Fig. 4, EDMG header 406 may include a total of 6 octets or 48 bits

[00204] In some demonstrative embodiments, as shown in Fig. 4, the non-EDMG header 404 may be "appended" with 48 bits of the EDMG-Header-A 406, e.g., corresponding to the first 48 bits of a data field of the PPDU, for example, to form a sequence of 88 bits (11 octets) of first codeword 402, which may be encoded with a code, e.g., an LDPC code, differentially encoded, spread by a factor of 32, and/or modulated (e.g., pi/2-DBPSK) for transmission.

[00205] In some demonstrative embodiments, as shown in Fig. 4, the EDMG-Header- A 406 of the EDMG PPDU may follow, e.g., may immediately follow, the L-Header 404.

[00206] In some demonstrative embodiments, it may be advantageous to exploit the sequential order of the L-Header and the EDMG-Header-A, for example, to define that the EDMG-Header-A 406 would be transmitted in the same LDPC codeword 402 as the L-Header 404. For example, such a configuration may allow an EDMG station to have access to a non-EDMG header 404 and an EDMG header, e.g., the EDMG- Header-A 406, if present, for example, even by decoding a single LDPC codeword, e.g., codeword 402. This ability may, for example, provide a technical advantage, for example, at least as it may allow reducing a delay/latency of a receiver processing.

[00207] In some demonstrative embodiments, a process of generating and transmitting the EDMG-Header-A, e.g., for Control Mode PPDUs and/or any other PPDU, in which the EDMG-Header-A is transmitted in the 6 octets of data that immediately follow the L-Header in the first LDPC codeword, e.g., the octets which may be used to carry 6 octets of data, e.g., in compliance with an IEEE 802. Had Specification, may allow both the L-Header 404 and EDMG-Header-A 406 to be signaled in the same codeword, e.g., codeword 402. [00208] In other embodiments, in some implementations, and/or use cases, only part of the EDMG-Header-A may be included as part of the first codeword 402, for example, if the EDMG-Header-A is longer than 6 octets. For example, the EDMG- Header-A may be configured to include a number and/or size of subfields, which may require more than 6 octets.

[00209] In some demonstrative embodiments, part of the EDMG-Header-A, for example, the HCS, may be transmitted in at least one additional codeword, e.g., the second codeword 320(Fig. 3), as described above.

[00210] Reference is made to Fig. 5, which schematically illustrates a method of transmitting an EDMG PPDU, in accordance with some demonstrative embodiments. For example, one or more of the operations of the method of Fig. 5 may be performed by one or more elements of a system, e.g., system 100 (Fig. 1), for example, one or more wireless devices, e.g., device 102 (Fig. 1), and/or device 140 (Fig. 1); a controller, e.g., controller 124 (Fig. 1), and/or controller 154 (Fig. 1); a radio, e.g., radio 114 (Fig. 1), and/or radio 144 (Fig. 1); a transmitter, e.g., transmitter 118 (Fig. 1), and/or transmitter 148 (Fig. 1); a receiver, e.g., receiver 116 (Fig. 1), and/or receiver 146 (Fig. 1); and/or a message processor, e.g., message processor 128 (Fig. 1), and/or message processor 158 (Fig. 1).

[00211] As indicated at block 502, the method may include generating a plurality of codewords based on an EDMG PPDU by assigning a non-EDMG header (L-Header) of the EDMG PPDU to a first codeword, assigning one or more first subfields of an EDMG header of the EDMG PPDU to the first codeword, and assigning one or more second subfields of the EDMG header to a second codeword. For example, controller 124 (Fig. 1) may control cause and/or trigger device 102 (Fig. 1) to generate a plurality of codewords, including codewords 301 and 320 (Fig. 3), based on EDMG PPDU 200 (Fig. 2), for example, by assigning the non-EDMG header (L-Header) 206 (Fig. 2) of the EDMG PPDU 200 (Fig. 2) to first codeword 301 (Fig. 3), assigning the one or more first subfields 304 (Fig. 3) of the EDMG header 212 (Fig. 2) of the EDMG PPDU 200 (Fig. 2) to the first codeword 301 (Fig. 3), and assigning the HCS subfield 318 (Fig. 3) of the EDMG header to the second codeword 320 (Fig. 3), e.g., as described above. [00212] As indicated at block 504, the method may include transmitting the EDMG PPDU based on the plurality of codewords. For example, controller 124 (Fig. 1) may control cause and/or trigger device 102 (Fig. 1) to transmit the EDMG PPDU based on the plurality of codewords, e.g., as described above.

[00213] Reference is made to Fig. 6, which schematically illustrates a method of receiving an EDMG PPDU. For example, one or more of the operations of the method of Fig. 6 may be performed by one or more elements of a system, e.g., system 100 (Fig. 1), for example, one or more wireless devices, e.g., device 102 (Fig. 1), and/or device 140 (Fig. 1); a controller, e.g., controller 124 (Fig. 1), and/or controller 154 (Fig. 1); a radio, e.g., radio 114 (Fig. 1), and/or radio 144 (Fig. 1); a transmitter, e.g., transmitter 118 (Fig. 1), and/or transmitter 148 (Fig. 1); a receiver, e.g., receiver 116 (Fig. 1), and/or receiver 146 (Fig. 1); and/or a message processor, e.g., message processor 128 (Fig. 1), and/or message processor 158 (Fig. 1).

[00214] As indicated at block 602, the method may include processing receipt of a transmission of a plurality of codewords of an EDMG PPDU. For example, controller 154 (Fig. 1) may control cause and/or trigger device 140 (Fig. 1) to process the receipt of the transmission of the plurality of codewords of the EDMG PPDU, e.g., as described above.

[00215] As indicated at block 604, the method may include decoding a non-EDMG Header (L-Header) of the EDMG PPDU from a first codeword of the plurality of codewords. For example, controller 154 (Fig. 1) may control cause and/or trigger device 140 (Fig. 1) to decode the non-EDMG header (L-Header) 206 (Fig. 2) of the EDMG PPDU 200 (Fig. 2) from the first codeword 301 (Fig. 3), e.g., as described above.

[00216] As indicated at block 606, the method may include decoding one or more first subfields of an EDMG header of the EDMG PPDU from the first codeword. For example, controller 154 (Fig. 1) may control cause and/or trigger device 140 (Fig. 1) to decode first subfields 304 (Fig. 3) of the EDMG header 212 (Fig. 2) of the EDMG PPDU 200 (Fig. 2) from the first codeword 301 (Fig. 3), e.g., as described above.

[00217] As indicated at block 608, the method may include decoding one or more second subfields of the EDMG header from a second codeword of the plurality of codewords. For example, controller 154 (Fig. 1) may control cause and/or trigger device 140 (Fig. 1) to decode the HCS subfield 318 (Fig. 3) of the EDMG header 212 (Fig. 2) from the second codeword 320 (Fig. 3), e.g., as described above.
